For v.20 users only

Easily and safely downgrade to 1.50! Simply select downgrade, and launch the 1.50 update from the PSP menu afterwards!
Change Gameboot
- Change Gameboot = copies the Gameboot.pmf from ms0:/Gameboot.pmf into the flash
- Backup Gameboot = copies the Gameboot.pmf from the flash into ms0:/Gameboot.pmf
- Restore original Gameboot = Restores the old gameboot.pmf

Firmware Tweaks
- Set Version 1.00 - 2.5 = Sets your PSP Version to 2.5. You can now also play games which require 2.5

Change X-O-Buttons
Before using this please restore factory settings
- Set X as enter (US / EU) = now X = enter at the psp menu
- Set = as Enter (jp) = now O = enter at the psp menu

If anyone is interested I have just downgraded my Psp 1006 v2.0 using the downloader at the link below.

The download even includes a video walkthrough and also automatically installs the tif and bin files in the right places. This has got to be the easiest ever.

The post that i edited..

Yeah i've done this. Basically all it does is fool the psp that its actually got v1 firmware so you can go launch the 1.5 update from your mem stick.

Mine got tp 99%, said updated failed, I rebooted and it said there were some corrupt settings press "O" to restore and it restores back to 1.5.

I looked at the video provided by Salvadali, the way i did it sems a lot more straight forward.

Can I just warn people that when you downgrade you get a trojan warning from Norton AV. Further investigations on the net may tell you that this trojan will brick you PSP. However, this is a red herring. I think the bottom line is you should always use TRUSTED sources for your downgrade files and you should be ok.

See the full downgrade thread for more info...

This app works great, i have downgraded afew times now with pspsetx0.2 and it has been fine everytime. No hassle at all. hit downgrade, quit app, browse to update folder and run 1.5 update file and your done.
